This command is supported on distributed devices and IRF-capable centralized devices.
Specify traffic processing slots if a feature requires that all traffic on a VA interface be processed on
the same slot.
For high availability, you can specify one primary and one backup traffic processing slot by using
the service command and the service standby command, respectively.
To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you
specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot
immediately after you specify the primary slot.
If you specify both primary and backup slots for an interface, traffic on that interface is processed as
follows:
• The backup slot takes over when the primary slot becomes unavailable. The backup slot
continues to process traffic for the interface after the primary slot becomes available again. The
switchover will not occur until the backup slot becomes unavailable.
• When no specified traffic processing slots are available, the traffic is processed on the slot at
which it arrives. Then, the processing slot that first becomes available again takes over.
If you do not specify a primary or a backup traffic processing slot for an i nterface, traffic on that
interface is processed on the slot at which the traffic arrives.
Examples
# (Distributed devices in standalone mode.) Specify slot 2 as the primary traffic processing slot for
the VA interfaces on Virtual-Template 10. Specify slot 3 as the backup traffic processing slot for the
VA interfaces on Virtual-Template 10.
<Sysname> system-view
[Sysname] interface virtual-template 10
[Sysname-Virtual-Template10] service slot 2
[Sysname-Virtual-Template10] service standby slot 3
# (Centralized devices in IRF mode.) Specify slot 2 as the primary traffic processing slot for the VA
interfaces on Virtual-Template 10. Specify slot 3 as the backup traffic processing slot for the VA
interfaces on Virtual-Template 10.
<Sysname> system-view
[Sysname] interface virtual-template 10
[Sysname-Virtual-Template10] service slot 2
[Sysname-Virtual-Template10] service standby slot 3
# (Distributed devices in RF mode.) Specify slot 2 on IRF member device 2 as the primary traffic
processing slot for the VA interfaces on Virtual-Template 10. Specify slot 3 on IRF member device 2
as the backup traffic processing slot for the VA interfaces on Virtual-Template 10.
